`Brain.users()` claims it returns an Array but returns an Object

Line 160 in f212f5d

 // Public: Get an Array of User objects stored in the brain. 

When attempting to use .forEach on the return result, it causes an error since it's not an Array. A fix could either be extracting all the Users into an Array to return or change the promise of what the function should return.

I'll update the comment.
